Week 3

Learning about Orsted's offshore wind farm project in Changhua.

July 8 - Wind Energy in Taiwan, Changhua Environmental Protection Union & Baguashan Eco-Tour

by Madison

Our first day in Changhua started off at the National Changhua University of Education, where we listened to a presentation on offshore wind energy development. Our speakers were a public relations officer and a technical expert from the Orsted Energy Company. Pictured here is Tony Lee, an electrical engineer, who was in the process of explaining to us the size of the offshore wind turbines being installed in Taiwan and their energy potential.

Local Means to a Global End: A Day of Conflicting Perspectives Over Offshore Wind Energy Development

For those of us in the environmental field, we often worry about job prospects. To quell our fears (and the fears of our parents), a very wise mentor and professor of mine once told me: there will always be environmental jobs, because creating environmental problems is something humans do best. Even when we “solve” a problem, we create a new one. Today when listening to the contradictory perspectives of the Environmental Protection Union, the Orsted Energy Company, and a green homeowner, this sentiment became animated by real life examples.

After meeting new friends at the National Changhua University of Education, our first academic day in Changhua began with a lightning bolt of energy storming the room, demanding our attention. She was charismatic, light in spirit, but assertive with her words. This woman was a public relations associate with the Orsted Energy Company—which was the perfect position for someone so personable and persuasive. We learned from her that Orsted initially began as an oil and gas company, but then transitioned to renewable energy sources in the 1990’s. Today, Orsted invests in offshore and onshore wind energy and bioenergy. However, for the purpose of today’s presentation, the focus was on offshore wind energy—a largely untapped global energy resource, but not without its baggage.

Orsted is responsible for developing offshore wind energy farms throughout the world, even off the east coast of the United States. Despite its global reach, Orsted is rooted in Taiwan, with multiple projects up and down the coastlines. I was curious at the onset of this discussion about what local communities thought of offshore wind farms because I’m aware of the political heat they receive in the U.S. For example, during my class on environmental conflict management and resolution taught by Clare Ryan back at the University of Washington, we learned about a contentious wind energy case in Cape Cod. I was charged with facilitating a mock negotiation exercise surrounding the proposed Cape Wind project in Nantucket Sound, Massachusetts. This required me to consider the interests of local residents, fishermen, ecologists, economists, and the government and to help the majority of the parties involved agree upon an acceptable compromise. The fishermen were concerned that the wind farms would adversely affect fish stocks, while the residents were disturbed by the thought of seeing turbines as their view instead of a pristine body of water. In the end, we agreed upon an iterative development approach that gave ecologists enough time to adequately assess the effects on the local ecosystem, economists time and resources to see how local communities could be adversely affected, and eased residents into the idea of a slight change in scenery.

Though this is what my group decided in the simulation, in actuality the project did not move forward because of rampant public animosity. I asked the Orsted representative how they negotiated with local communities, and she responded with a video. This video showed an overwhelmingly positive outlook on offshore wind energy development. Most people were hesitant at first, because change is something we are all innately uncomfortable with, but over time communities adjusted and thrived. Fishermen transitioned to flexible desk jobs and earned a stable, higher income. I am skeptical that this video portrayed the full story, for I know that fishermen are usually continuing an intergenerational culture with their line of work. They have a lot of pride surrounding their chosen profession. Switching to a job with less freedom could be a compromise they are uneasy to make. Though this is a green energy company, it still leverages capitalistic marketing strategies to sell their product. In this case, a more sustainable future—but is there a cost to local communities that is being silenced in the process?

Though renewable energy development will reduce the severity of climate change on a global scale, this does not make this industry immune from environmental degradation at the local level. And when thinking about what counts as the “environment,” local communities must be included in this definition. The latter half of Orsted’s presentation was spearheaded by an electrical engineer and teacher named Tony Lee (see image). He spent much of his interactive presentation detailing how their turbine design was environmentally sound. For example, instead of installing the turbines using the cheapest method of hydraulic drilling, they install a jagged, pyramid-like support platform. The former method produces significant noise pollution, while the latter is quieter and allows for marine organisms to aggregate on the base of the structure, theoretically increasing biodiversity. This means that local fish populations could be bolstered, therefore increasing revenue for fishermen. Additionally, during installation they shield out noise with a bubble curtain. This reduces the harm to marine mammals—such as the white dolphin, endemic to the Taiwan Strait and already threatened by anthropogenic influences. Lastly, the layout of the turbines in theory should allow for birds to safely pass through the wind farm, reducing collisions. We were sold an ideal vision of renewable energy compatible with the local ecosystem.

Our next lecture, headed by Dr. Tsai of the Environmental Protection Union, directly contradicted our first lecture of the day. He gave us a broad overview of environmental conflicts in Taiwan—including how renewable energy development can have adverse local effects. Later in the week, Dr. Tsai took a small group of us to see the Industrial Zone, which was a politically charged place that he referenced in his Monday lecture. Pictured on the right is a massive wind turbine, slicing through the air directly above a Little Tern nest in the sand. These little birds made this place their new home after artificial sand dunes were created from development; however, the turbines are organized in such a way to not allow the birds safe passage through the zone. People will often find dead birds below the turbines, cut by their swift revolutions. This is just one of many environmental conflicts that exist on the Changhua coast.

I bought every word Orsted said—until we heard the other unspoken side of the story. We were transported to Baguashan, where we listened to a talk by Dr. Tsai of the Environmental Protection Union on coastal environmental challenges in Taiwan. He covered a lot of ground, describing the diversity of coastal environments found along the 13,000 km of shorelines encircling Taiwan and case studies related to industrial development. He began with a story about the Changhua Industrial Zone, which is a 30,000-hectare area of land that was reclaimed by the government and turned into a multiuse area for industry and renewable energy—specifically solar and wind energy. I didn’t quite understand what Dr. Tsai was describing until I got the opportunity to visit the Industrial Zone at the end of our week in Changhua (see image). Once an expansive mudflat harboring oyster aquaculture, mangrove trees, and a rich swath of biodiversity, this area was now a sandy, mostly unutilized area dotted with wind turbines and solar panels. Apparently, the land was too expensive for industries to develop, so for the most part the land was left bare. Upon arrival we saw a small nest of little tern eggs, with their parents hovering in the sky above, battling the wind. Destroying the mudflats and creating a new type of area inadvertently attracted these little birds, which are often killed by the turbines. From the perspective of Dr. Tsai, altering the land in this way was irresponsible, and in his words, “just stupid.” He approves of renewable energy development, so long as it doesn’t sacrifice the integrity of local environments.

This was the point at which he began to criticize Orsted’s plan to develop an offshore wind energy farm. Though white dolphins were mentioned in the morning as a species that could be affected by development, the issue was brushed aside without a second mention. However, Dr. Tsai made it abundantly clear that this isn’t a negligible issue—in fact, white dolphins are an endangered and culturally important creature to many Taiwanese citizens. When hearing this, I couldn’t help but see the white dolphins as analogous to our Southern Resident Killer Whales in the Puget Sound. A subspecies of orca whales, they only exist in our waters. They are threatened by an onslaught of anthropogenic factors, including noise pollution from ocean vessels and the navy, starvation from reduced salmon runs, industrial pollution, and crowding from tourism. White dolphins, on the other hand, only live in the Taiwan Strait between China and Taiwan, and are affected by marine debris causing lacerations, vessel traffic, industrial pollutants, and noise pollution. Activists are concerned that underwater noise pollution from drilling could cause disruption or hearing loss, thus tipping the dolphins over the edge of what they can handle. Orsted’s mitigative plans aren’t good enough.

In this situation, what activists want is more time for scientists to study the effects of offshore wind energy on the white dolphin population. Like in my simulation of Cape Wind, for all parties to be comfortable with the social and environmental impacts associated with development, they would like there to be more information about these potential effects. But the Taiwanese government has put a clock on construction, rushing ahead with renewable energy installation and forgoing these more thorough studies. This is because, much at the behest of Taiwanese citizens, the government is pursuing a policy of denuclearization by 2025. To meet the high energy needs of city centers, they are racing to find clean alternatives. However, people are worried about the consequences of premature action.

Besides conducting a thorough environmental assessment on areas to be developed, another way to reduce negative local impacts is to tackle the problem at the source. To reduce energy consumption. Our third presenter of the day, Marty Shieh, has made it his life mission to challenge himself to the extreme to do just this (see image). Besides making every choice guided by environmental ethics, Marty endeavored to design and build a house that significantly lowered the carbon footprint of households. He dug underground, utilizing the natural cooling capabilities of the soil to eliminate the need for an air conditioner. He insulated walls with air pockets, which when heated would rise up and out of the house. Marty created simulations of his house and tested how the angle of the sun throughout the day would affect how much natural light would penetrate through windows or solar panels. In the end, his household only needed to consume 1000 units of electricity from the power grid—which is significantly less than the average household. He stated that at our current consumption rate, we need 20 earths to sustain our lifestyle. And yet we only have one. We can’t purchase another planet and call it good. Somehow, soon, we need to figure out how to integrate ourselves back into ecological systems in order to keep calling this planet our home.

Our third and final guest lecturer of the day, Marty Shieh, told us his story about his lifestyle as an avid environmentalist and how he designed and build a green home. Pictured here is the layout of his home. As you can see, it is partially built underground; this serves the purpose of maximizing efficient air circulation and eliminating the need for an air conditioner.

Reducing our consumption rate requires every person to make choices with the environment in mind. To alter their own personal behavior, challenging habits. But change also comes from the top-down. Our last portion of the day was spent touring Baguashan, and at one point we summitted a hill to witness a panoramic view of Changhua and Taichung. From here I could see the infamous Taichung Coal Power Plant, whose four smokestacks jutted up from the horizon (see image). Though this country is starting to be seen by the world as a leader in sustainability, it still is home to one of the largest coal power plants in the world. Taiwan, like most other places in the world, struggles with abusing the local land for profit, or even in the pursuance of larger goals such as tackling climate change. If we as a global people want to build a sustainable present and future, both local and global aims must be balanced. We need radical action to develop green energy solutions, but we also need to foster diverse, resilient communities. This ensures that when the time comes to adapt to change, we can handle it. Our local environments will be able to buffer the harm, and community cultural integrity will help us face what we must endure. I am thankful for this day of conflicting perspectives, for controversies even within the environmental movement help me be able to see an alternative path for moving forward.

At the end of the day, Marty Shieh guided us through Baguashan, taking us to his eco-home, through underground tunnels, and to the top of a hill to see a panoramic view of Changhua alongside the massive Baguashan Buddha. One site in particular caught my attention—the Taichung coal power plant. This power station is one of the top 10 largest coal power plants in the world, and is a reminder of how even a country that is starting to be recognized as a world leader in environmentalism still has a massive amount of work to do to live that truth.

Students assembled a solar PV module and learned about the technical aspect of solar energy generation.

July 9 - NCUE Renewable Energy Research Center & Energy Transition Policies

by Yuxuan

Carrying solar panels to the rooftop. Prof. Chen (walking in front of the team) introduced general PV technology before we worked on the installation.

NCUE Renewable Energy Research Center

After studying wind power and environmental concerns related to renewable energy the day before, we came to the Renewable Energy Research Center at NCUE. Our focus included both theoretical knowledge related to solar cells and hands-on experience to install solar panels. Special thanks to Prof. Chen and two of his graduate students from the Department of Electrical Engineering of NCUE, who made this precious learning experience possible.

Carrying solar panels to the rooftop, the sudden rain did not comply with the agenda. We came back to the roof when the rain was gone, during which we listened to an informative lecture about the fundamentals of solar cells, which will be detailed later. TAs gave us step-by-step detailed instructions about setting up racking system and securing an array of solar panels. Three stands were each formed by one medium-length beam and two short beams (all in aluminum). Those beams were connected through bolts and nuts, which required the use of wrench. One special type of wrench, which was nicknamed “kari kari”, was interesting. It was locked when turned in one direction and loose in the other so that the user can drive the bolt without adjusting the position of the wrench after one turn. Three long beams were connected in perpendicular to those stands to form the frame of the racking. Each racking was supposed to hold four solar modules and four clips for each module were installed on the long beams. After inserting solar panels in the clips, we secured them by fixing those clips through tightening bolts pre-installed on those clips. There we were, two groups of UW/NCUE student teams, setting up two solar arrays with around 2 kW capacity in total.

Working on the installation was a brand-new experience for all of us, even for those who had previous knowledge about solar energy. We realized installing those modules could be not so challenging and even fun. This “rooftop class” also gave us a better idea about the physical reality of the solar array system so that we can promote solar energy to others with a clearer picture in mind.

During the lecture, Prof. Chen first briefly introduced how solar cells work and different types of solar cells. Based on the fact that our group was interested more in the environmental impact of solar energy, Prof. Chen made several important points:

● Most solar panels use pure Si as the material for their active layer, which is not toxic by itself. For recycling, we could simply separate Si with other materials (Cu wires and glass, etc.) and remelt Si for other usage.

● The fabrication of Si wafer (necessary step for manufacturing solar panels), however, is very energy-intensive. The energy consumption comes from heating Si beyond its melting point (over 1400 °C) and staying for 6 to 10 hours for further treatment.

● There were efforts to replace silicon-based solar panels with other materials, but none of them turned out to be feasible. For instance, CdTe solar panels could be printed and reduced the cost, but Cd is a heavy metal and hard to dispose. CIGS solar cells could potentially have better performance, but it uses expensive element and its efficiency remains problematic.

● Organic semiconductors are emerging as promising candidates for optoelectronic applications. However, the strength of chemical bonds within organic materials makes the longevity of solar panels using those materials much shorter than expected for their counterparts made out of inorganic semiconductors.

In conclusion, visiting NCUE Renewable Energy Research Center was an eye-opening experience for our group. We were thankful to have the opportunity to learn about solar energy from the research and practical perspective.

Almost done! NCUE and UW students teamed up to build two solar arrays (four panels in an array).

Energy Transition for Taiwan

After the lunch break, Dr. Ker-hsuan Chien from NCUE gave us an overview about renewable energy development in Taiwan, specifically focusing on the energy transition. The lecture put renewable energy in a bigger picture and discussed several social and economical concepts surrounding renewable energy. Renewable energy, as part of the “Cleantech”, is viewed as a promising mechanism to promote the “New Economy”. However, whether Cleantech is really clean, or it was simply utilized by some capitalists to make quick money, remains suspicious for the industry and environmentalists.

Using wind energy as an example, wind developers are eager to invest in the wind energy market of Taiwan, but environmental groups are making an effort to slow down the development until a comprehensive environmental impact analysis for those wind farms could be conducted. Those companies were attracted by the Feed-in-Tariff (FIT) announced by the current Taiwanese government, which allows them to sell electricity at a much higher rate than the electricity retail rate in Taiwan. Those developers claimed that they asked third parties to conduct environmental analysis, but environmentalists believed those results were biased to achieve desired conclusions. The aggressive movement of wind developers can be viewed as the downside of the FIT policy. Admittedly, FIT can protect emerging technology from being suffocated by its mature but less advanced counterpart, but it is not so helpful for boosting the actual competitiveness of the new technology. In addition, with Taipower as the energy monopoly in this island, using Renewable Energy Credit regulation to require utility companies to purchase and even commercialize renewable energy generation is impossible to implement.

Solar energy also has to deal with the power of capitalism. Although tools were invented to finance the development of new solar arrays, they might have a negative impact on the industry. For instance, a developer in the U.S. set up a platform to connect solar investors with stakeholders so that house owners lent their roof to get cheaper utility bills and solar investors invest and own solar panels for profit. However, the involvement of multiple parties could boost the total cost of a solar array system and makes the electricity generated by solar less competitive with that from other sources.

In conclusion, both indoor and outdoor study throughout the day were fruitful for all of us. From the technology level to the policy level, we had a more comprehensive understanding about renewable energy, especially solar and wind energy. Starting from there, hopefully, some of us would be inspired to pursue a career in a field related to renewable energy.

Dr. Ker-hsuan Chien discussed different aspects of renewable energy development in Taiwan.

Learning about the history and future visions of Taichung City.

July 10 - Taichung Tour: Urban Center Renewal

by Charlie

This is a picture of everyone grouping in the front door ready for the class of the start of the great morning learning the background story of Taichung.

Today we took an hour bus trip to Taichung, which is the central part of Taiwan. As we arrive at Taichung, there is more public transportation compared to Changhua. Some people were appealed to the BRT system that the Taichung government set up a dedicated bus lane for part of the buses which is a pretty similar design copied from Taipei. Arriving at the city hall, I noticed a large amount of open green spaces and street trees all around the blocks which there is a different perspective of Taichung that I have never thought about.

Entering the green building, we started to visit the history of Taichung. Our guide started with some question giving us some background knowledge of Taichung which one of them is asking what is the ranking of Taichung city. Usually, people will think that Taipei and Kaohsiung are the two largest cities in Taiwan since they are much more well known than Taichung international-wise which many of us replied the third place. However, the guide told us that actually, Taichung is the second biggest city which included a county and a city keeping up with Taipei. We started the exhibition with for different perspectives - Taichung vision, Taichung history, Taichung City Story, Taichung Life. Firstly, Taichung vision including four values creating strong connections in the community, friendly with a new immigrant, smart and clean environment, and a suitable environment for newborn baby. To fulfill some of the value, the city started some innovative policy which is combining the new and old city, Big Taichung “one-two and three”, creating a residential place, and suburban revitalization which makes Taichung the best and suitable city to live in Taiwan. The first display in the exhibition is a large wall when entering the entrance which it plays the video of the evolution of Taichung including making an eco-friendly environment for forest all around, creating greater and human-friendly harbors, airports, and transportation and a better city center. I believe the MRT and BRT system operating system fulfilled all the conditions above and create a wonderful public interaction in Taichung.

Secondly, walking to the historical part, we started with a big map drawn by Chan Yi Chung a famous architect. He demonstrated Taichung by dividing it into four parts - Mountain, Sea, Tun-district, and City. Looking with our bare eyes we could somehow learn and know the future image of Taichung, although as a Taichung citizen this map has tons of flaws. On the other hand, observing through their app, we discovered Taichung's four significant historical events and understood the connection between the present and past of Taichung City. City history is the accumulation of various ethnic groups and their shared public life. I could recall in one of the areas explained Taichung's municipal path and abundant civilization over thousands of years of history, from prehistoric to contemporary. Besides that there is a "Time Capsule of Taichung" describes the location story, from the beginning of the Earth to the diversity of Taichung citizens and their interaction with the lands, gradually indicates to us audiences changes in Taichung City and its appearance. I remember interacting with a wall full of pictures with many different place names. By taking the same angle and same place, there is a strong comparison which the audience could witness the differences in the appearance of the past and present. Through the applications on walls and the maps, we discovered many historical events, major areas, the connection between the past and present in Taichung which combines with some activities in the evening.

A picture of Taichung in the near future with BRT and MRT done built and the harbor.

The third significant characteristic of Taichung is the story of the city. In the city build-up of a pleasant climate, a population over 2.5 million people, making it the second-largest city in the country after New Taipei city. In 1705, Taichung is founded in part of Changhua County which originally named Dadun (大墩). During the Qing Dynasty invaded by Manchus consolidated the families in the western center of Taiwan which is the Cheng family. Under this circumstance more and more Han people started immigrating to Taichung which form a bigger centered town. However, in 1895, China lost the Sino-Japanese War which Taiwan is forced to be ceded to the Japanese under the Treaty of Shimonoseki. Dadun has changed its name to Taichū and started to develop as a city, setting up the first "modern" area of Taiwan. Although there is some rebel against the Japanese government, the Japanese still had great plans in Taichung such as setting Taichung station as the central of Taichung, or like great architecture that is useful until nowadays. Then the Republic of China came merging Taichung City and County of Taiwan Province into a new a special municipality of Taichung which created more interactions in between the city and county there is the world-class science museum, the quality National Taiwan Museum of Fine Arts, the colors of the Rainbow Village, the stunning architecture at the National Taichung Theater. Here people could also enjoy delicious food and drink, and find cheap and interesting items for sale. These include Yizhong Night Market (一中夜市), Feng Chia Night Market (逢甲夜市), Tunghai Night Market (東海夜市), and Zhongxiao Night Market (忠孝夜市)......etc which builds up Taichung a significant city in Taiwan. Last but not least, According to history and the story of Taichung, the government is changing the city into a smart city. From the coastline to city buildings, farm fields to mountains, the government started to build up bicycle trails, national parks. We directly run to the upright bike enjoying the image created by the simulator of the cycling trails. If possible I will try to go there myself bring my friends and family to re-recognize Taichung.

As we finished lunch around the traditional market, we visited the Taichung Literature Museum. The guide started talking about the history of the architecture which is used to be a police quarter during the Japanese colonial period. It includes 6 different buildings - the administration, themed dining area, workshops and lectures, exhibitions, children’s literature. After introducing each building, the style of architecture draws my attention - architectural concrete by Tadao Ando. Creating the spiral twisting lines on the concrete wall while maintaining the appearance of simplicity, he tries to emphasize the nothingness and empty space in all his masterpiece including the one we visit.

We had a good day in the morning, but a pretty messed up the afternoon with the poem because there is no translation for it. I understand it is for promoting the literature of Chinese, but I think for a non-Chinese speaker will need half an hour to understand a piece of poem.

This is our guide who taught us some poems and Chinese phrase and I tried to translate the poems my best.

This wall special design present - 稿紙 the Chinese paper that we usually write on. The blocks were for every single Chinese character.

Harvesting vegetables at Ta-Yu Community Garden.

July 12 - Field Trip along the Coast of Changhua (Ta-Yu Community & Fang-Yuan Mudflats)

by May and Idan

The first half of our day was a visit to the Ta-Yu farm with the NCUE students. This event was under the Ta-Yu Community Development Association and they invite the general public to experience farm work and rural culture. We started off the day bright and early at 7:20AM and arrived at the farm. Our tour guide gave us an hour to paint our own straw hats however we liked and we got to use those during our farm work (this is also when I discovered how artistic some of our classmates were).

Next, we were led on a tour of a family whose houses resided on the farm. We visited their old and new house and learned some cultural significances of building designs. For example, the old house had square tiles, which signified a public space. This was fitting, since these tiles were in the court grounds of the house. In the new house, they had hexagon tiles which represented the back of turtles. Since turtles have long lives, these tiles signified longevity of the family.

One cultural significance of the houses were their window frames. Both houses had an odd number of columns between their windows. This is due to the believes that an even number is related to bad spirits. Another belief is that there are certain things the family can do to conceive boys in the future, such as hanging lights in front of their alters.

This is the court ground tiles of the new house (notice the hexagon shapes). Some people thought they looked like beehives while others thought it represented the number 6. Nope! They’re actually turtles for longevity!

These are the odd numbered columns in windows. Even numbers are associated with bad spirits and bad fortune, which is why all these windows avoid having an even number of columns.

After the tour, we were lea to the farms where some elders (Team Best Grandpa!) took us to harvest vegetables. We also tilled the land, spread seeds, and watered our lands. Something interesting about the farm is the way they avoid using pesticides. The farmers raise ducks that eat the bugs from plants and the duck poop they leave behind also serves as fertilizer to help plant growth. By doing this, they save on the need to spray pesticides and the cost of purchasing fertilizers. The ducks produce ducklings and when they get old, become food for the farmers.

With the vegetables we harvested, the grandmas taught us how to clean, wash, and cut them. With the traditional way of lighting a stove, we learned how to season them and cooked plates of vegetables for all of us. For some of us, it was our first time cooking and working with a different type of vegetable. So this was a valuable life skill to take back with us to Seattle!

This experience was really eye-opening for me because it showed that having a small plot of land for growing vegetables is something most of us can do, even if it’s on a balcony. We can all try to live more sustainably by producing our own food because what is more local than growing from your own yard?

The second half of our day consisted of visiting the mudflats in Changhua’s coastal area. Dr. Chia-Yang Tsai knowledgeably informed us that this area is home to the largest mudflats in all of Taiwan and if the EPA had not insisted on preserving it, it would instead be home to a petrochemical enterprise like the one framing the skyline, known as Formosa Plastic Petrochemical Company. This is the largest petrochemical plant in Taiwan.

This area is open for the public to explore and I personally had a great time wading through the muddy terrain. I was finally able to put my rainboots to some good use! Upon exploring the area, I was shocked to discover how many species live in this ecosystem. Many were crabs but even they differed from one another. Dr. Tsai picked up at least 3 different types of crabs which he identified as Big Eyes Crab, Northern Findeler Crab, and Spider Crab, which he nicknamed “Marching Soldiers.” I was not surprised by the name choice after seeing them all quickly shuffle in groups. They truly did look like a herd of warriors crawling away! Unlike other crabs, they have spider like legs that enable them to crawl forwards rather than sideways. It was really a unique sight that made me realize how important wetlands are. Even the housing materials that people discarded into the ocean have washed up and provided a home for some of the crabs that prefer the muddier areas. It was astonishing to learn that even when polluted, these mudflats still served their purpose and provide a habitat to a multitude of species. Note: POLLUTING THE OCEAN IS STILL NOT OKAY

Pictured here are the shoes that are most commonly worn by fishermen who work in the coast and on these mudflats. They have rubber soles and a net sock-like structure that allows water to seep through. The individual pictured with them made sure to mention the funny tan lines that result from such netting.

This image portrays the coastal mudflats along with wind turbines generating green energy in the background and fishermen, farming for oysters. Pictured here is also the truck used to farm the oysters in Changhua as mentioned in the blog.

Another type of species that rely on this environment are oysters! After walking farther into the mudflats which span about 5 km until they reach the sea, we came across an oyster farm. Dr. Tsai told us that while the tide is high – every 6 hours, twice a day – the oysters feed on the sea water, and while the tide is low, such as it was during our visit, they close up and take a rest. We also learned that the oysters who are closer to the sea-line are better off, as they get longer exposure to water during high tides and thus more feeding time. We even met a fisherman who had collected oysters and kindly let our group try some fresh ones! I personally do not like oysters so I did not try one, but those who did claimed that they tasted milky and salty, and that the oyster itself had no odor. The consensus for the Changhua oysters therefore was a positive one!

Dr. Tsai briefly mentioned Chiayi’s oyster farms and mudflats, and identified some differences from Changhua’s, such as the oyster farming methods. Whereas Changhua relies on trucks to collect oysters, Chiayi uses a boat.

Although the experience was long and the sun exposure was intense, I had a wonderful time and would definitely recommend for anyone to come and explore this biodiverse ecosystem. Mudflats and mangroves (which we walked through) are extremely important to our environment and what better way to learn about them than to explore one! Dr. Tsai’s passion for this area was also a bonus!

Disclaimer: Unfortunately, our group grew extremely tired and many of us have returned to our hostel without visiting the industrial zone. Both May and I (Idan) returned so we do not have any recollection of the experience, but I am excited to hear from those who did not let the fatigue from the heat get to them and pushed on to discover Changhua’s other wondrous gems!

One of the collapsed classroom buildings preserved at the 921 Earthquake Museum.

July 13 - Field Trip to Nantou (Post-earthquake resilience & Checheng Timber Town)

by J. T. and Madison

Maddy and J.T. in front of the "9/21 Earthquake Museum of Taiwan" Sign

For our field trips on July 13, we started the day by visiting the 9/21 Earthquake Museum of Taiwan. When learning about the field trips we were going to go on during spring quarter, this one stood out the most to me and was the one I was most excited for. I was intrigued as to how they preserved all of the semi-collapsed structures and excited to see what an area so close to the epicenter of such a large earthquake looks like. All of my curiosity was only heightened since I'm from Colorado, thousands of miles away from the closest active fault line. I have always been fascinated by earthquakes while simultaneously knowing so little about them, with even less experience with them.

We started our tour of the museum by covering the different characteristics of earthquakes. We began by discussing the intensity of earthquakes and how much their magnitudes can vary. We were able to get an idea of just how strong they can be through a contest of strength of our own. The museum had a seismograph installed next to a table which we then took turns hitting to see how strong of an "earthquake" we could create. Yours truly started us off strong with a 6.4 and almost remained undefeated until Qi Ying came in at the end with a 7.3 and took the lead.

From there we proceeded to learn more about the difference between s-waves and p-waves, aftershocks, and the varying degrees of structure stability with a plethora of other interactive exhibits. Although I knew about earthquakes beforehand, most of what we learned about these topics was straightforward and could be logically deduced by most. However, one topic that both shocked and scared me was the aftershocks. The tour guide showed us a map that lit up all of the aftershocks in the days following the earthquake and it surprised me how they were all over the island. No corner of Taiwan didn't feel this earthquake or one of its aftershocks. This truly made it clear just how hard it is to prepare and predict earthquakes when they can have effects for such a long time afterward in such a large multitude of locations.

After these exhibits, we headed over to the most anticipated activity of the whole museum, the earthquake simulator. I had no idea what to expect for the simulator, but my immediate reflection after experiencing the shaking and simulated damage was that it was less intense than I expected. However, after discussing it with some of my peers, I hadn't taken into account that we were in a cushioned room, with nothing on the walls and we were sitting on the floor or in couches the whole time. When extrapolating the same shaking feeling to a real-life situation, the situation became much scarier in my mind. This simulation ended our trip to the 9/21 museum and from there we border our bus and headed to our next stop!

While on the bus, I thought about how even with the simulator, the images, statistics, and information that they provided us, I was having a hard time truly imagining how horrible this earthquake was for the locals and many throughout Taiwan. This pointed out to me just how important it is for us to remember and to continue to work to inform the public both locally and abroad. We live in a world where it is so easy to get desensitized to horrible news, natural disasters, and other's pain. However, I think it is important for us to keep on trying to feel for others and imagine what they have had to go through to give us the motivation to help and make a difference.

Still processing our experience at the Earthquake Museum, we headed to the mountains—more specifically, the timber township of Checheng in Nantou County. We have spent much of our trip in cities, so taking the time to venture to a place dripping with foliage was enriching in a different kind of way. As we climbed in elevation, I could see my classmate’s eyes lighting up with wonder at this new place, distinctive from all the other places we had visited previously. We were dropped off just above a jade blue-green river, flowing down from a hydropower plant and into the gully. Surrounded by towering hillsides that couldn’t fit in one photo frame and bustling tourists, we took it all in with our senses and cameras.

Unlike most other field excursions, we have gone on, our experience in Checheng was entirely unguided. Therefore, to discover the history of this place and what it has become, I gleaned information from the tourist village and the surrounding landscape. A railway separated the river from the town, and weathering box carts provided a lens into the past. The train, still active, takes tourists from Checheng to other nearby attractions, such as Sun Moon Lake. However, in the past I can imagine trains transporting stacks of freshly cut timber from the hillside down the mountain, on their way to the nearest port. As we had learned in class, when the Japanese empire occupied Taiwan from 1895-1945, they readily exploited the island for its natural resources. They scraped the hillsides bare for mineral deposits. They scoured through the forests for the most valuable trees. Although camphor trees, Taiwanese incense cedars, and common teaks were all harvested, one tree in particular was prized for its versatility and hardiness: the Taiwan red cypress.

Throughout Taiwan, one can see where this cypress tree has left its mark. In Miaoli county, there is an entire village that highlights the woodcarving culture of the region. Peering into each shop are dozens of stumps, each intricately carved and polished. It is not difficult to recognize the deep red-brown hue of the red cypress, molded by human hands into something new. Traditional medicines and essential oils are sold throughout Taiwan to cure anything from the common cold to bug bites. Cypress oil has a distinctively pungent smell, which simultaneously is soothing for the user and repulsive to bugs. The Taiwan red cypress is also spiritually essential for the people of Taiwan, representing a connection to God and the source of life itself. Considering how people from numerous ethnic groups call Taiwan home, one can only imagine the multiplicity of ways in which the Formosan cypress is valued by this island’s diverse inhabitants.

Even after the Japanese receded from Taiwan, logging continued in Checheng, creating jobs and bolstering the local economy. However, trees like the Taiwan red cypress were exploited to unsustainable levels, and in 1985 logging was banned in the region. Without revenue from timber, the township eventually leveraged its history to transform into a tourism hotspot. But the story of natural resource use in Checheng doesn’t stop there—in fact, one of the most scenic aspects of the township, the river, has been significantly altered by people. In the latter half of our time in Checheng, we hiked above the township through a forest of bamboo to witness the Checheng dam and Mingtan Hydropower Plant from above. Though the waters flowing down from the dam are vibrant with the hues of the stones they carry, the reservoir up top is a murky green-brown pool, bordered by powerlines running up and into the mountains. I remember seeing this from above when flying into Taiwan a month ago—powerlines radiating from the center of the island to major city centers. These rivers are powerful, and there are only so many places in Taiwan where current infrastructural designs can handle the deluge. At this point, the hydropower potential of Taiwan is mostly exploited, and if this island wants to continue on the path toward sustainable development, renewable energy, and environmental responsibility, it will need to turn toward other sources. But in the process, there will always be local impacts to development—even if it is labeled “green” development.

During the second leg of our day’s journey, we were given the freedom to roam around the historic lumber town, turned into tourist hub, of Checheng. Immediately after exiting the bus we were greeted with this image—massive hillsides of lush green foliage and a rushing river the color of blue-green jade. The beauty of the scenery, like many places in Taiwan, is juxtaposed by the human influence. Atop the hillside one can see a murky green reservoir, created by the Mingtan Hydropower Plant. And within in the mountains, powerlines.

When walking around the town of Checheng, the prolific art and products sold here make the identity of this town abundantly clear. Here we see the Taiwan Red Cypress, also known as the Formosan False Cyprus or the Tree of God. Cypress wood was extremely valuable for its structural integrity, but it also was culturally valuable to the people of Taiwan. One account stated that cypress is the guardian spirit of the land, and its deep and interweaving roots are the source of life.

Taiwan is a fascinating place because even in the face of captivating natural beauty, the human influence is always evident. Much of this has to do with Taiwan being an island, and space being limited. In the U.S., there are large swaths of land between environmental abuse and population centers; however, it takes just a turn in the road, a shift in perspective to see how humans have negatively affected the land and local residents alike here in Taiwan. There is no space for environmental conflicts to be out of sight and out of mind. Perhaps this is why many Taiwanese citizens and the government have been trying to lead the change for the future—because it is more than evident what overexploitation has done to this island ecosystem.

Because their home is beyond beautiful, and it is something worth protecting.
